[Qemu-devel] [PATCH] qmp-commands.hx: Update the supported 'transaction' operations |
Date: |
Fri, 2 Oct 2015 14:12:34 +0200 |
Although the canonical source of reference for QMP commands is
qapi-schema.json, for consistency's sake, update qmp-commands.hx to
state the list of supported transactionable operations, namely:
drive-backup
blockdev-backup
blockdev-snapshot-internal-sync
abort
block-dirty-bitmap-add
block-dirty-bitmap-clear
Also update the possible values for the "type" action array.

in its "v7" edition):
- Update the possible values for supported 'type' of operation
